Americans are now spending more time than ever on social media. Although that much is already obvious, what isn’t as transparent is just how much time the average American is spending on platforms like Facebook every day.

Today, however, we were given an answer to that burning social question directly from Facebook.

CEO Mark Zuckerberg admitted during Wednesday’s Q2 earnings call that the average user now spends 40 minutes per day glued to the site.

“Zuckerberg said that the 40 minutes a day on Facebook account for one in five minutes spent on mobile in the US,” reports TechCrunch. “Yet Facebook’s CEO sees plenty of room to grow, as he said that Americans spend about 9 hours per day engaging with digital media. Facebook has 204 million monthly users in the US and Canada.”

The social networking giant’s earnings topped projections for the 8th consecutive quarter with $2.91 billion in revenue.
